Question

我正在尝试将Gradle项目here集成到我的Maven项目中。文件data-context.xml用于配置Hibernate和Spring，以生成用于验证用户对RESTful接口的请求的存储库。

一切正常，但当我尝试部署到tomcat服务器上时，我看到以下问题：

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'securityContextFilter' defined in file [/var/lib/tomcat6/webapps/services/WEB-INF/classes/com/services/filter/SecurityContextFilter.class]: Unsatisfied dependency expressed through constructor argument with index 0 of type [com.services.user.UserRepository]: : Error creating bean with name 'userRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract com.services.user.domain.User com.services.user.UserRepository.findBySession(java.lang.String)!; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract com.services.user.domain.User com.services.user.UserRepository.findBySession(java.lang.String)!

对于初学者，我建议修复你的实体，你有一个基本的一对一映射，但你正在复杂的方式，你也不需要复合主键。接下来，您的查询也是复杂的，您不需要加入，只需从user返回AuthorizationToken字段。

实体

您的所有实体都直接或间接地扩展AbstractPersistable该类已有ID字段。不需要添加额外的@Id，并且只会混淆JPA，因为您现在突然需要复合主键。该解决方案非常容易从实体中删除自定义ID字段。

@Entity
@Table(name="rest_authorization_token")
public class AuthorizationToken extends AbstractPersistable<Long> {

    @Column(length=36)
    private String token;

    @OneToOne(fetch = FetchType.LAZY)
    @PrimaryKeyJoinColumn
    private User user;

}

AuthorizationToken无法嵌入，因此请删除注释。对于一对一映射，添加@PrimaryKeyJoinColumn注释。 token字段不一定是@Id，AbstractPersistable中已存在主键字段。

在User实体上删除@IdClass，因为简单映射不需要。如果您不想要双向关系，请从authorizationToken实体中删除User字段。如果您想使用它，只需删除@Id。

@Entity 
@Table(name="rest_user")
public class User extends BaseEntity {

    @OneToOne(fetch = FetchType.LAZY,
            mappedBy = "user",
            cascade = CascadeType.ALL)
    private AuthorizationToken authorizationToken;

}

注意：我省略了其余的实体代码，因为它保持不变。

现在已清理实体，只需返回user中的AuthorizationToken字段即可简化查询。

public interface UserRepository extends JpaRepository<User, Long> {

    User findByEmailAddress(String emailAddress);

    User findByUuid(String uuid);

    @Query("select user from AuthorizationToken where lastUpdated < ?")
    List<User> findByExpiredSession(Date lastUpdated);

    @Query("select user from AuthorizationToken where token = ?")
    User findBySession(String token);

}

我还注意到，由于Spring Data JPA可以为您生成该查询，因此您不需要@Query findByUuid。
